Background and Objective: The aim of this study was to determine the level of plasma high sensitive c-reactive protein (hs-CRP) in preeclampsia and to compare hs-CRP levels between normal pregnant women, mild preeclamptic, and severe preeclamptic women. Materials and Methods: Serum hs-CRP levels were inv...
the application of a comprehensive model of communicative language ability (cla) to language teaching and testing has always been an imperative in l2 education since hymess proposal of communicative competence in the 1970s. recent l2 research has clearly underscored the importance of sufficient pragmatics representation as an essential component of cla in pedagogical and testing practices in l2...

N-(2H-[1,2,4]thiadiazolo[2,3-a]pyridine-2-ylidene)benzamide was used as a selective sensing material in the PVC membrane to construction of a new chromium ion selective electrode. This liquid membrane electrode worked well with a Nernstian response of 19.7 ±0.4 mV decade-1 of Cr(III) in a wide dynamic concentration range of 8.0× 10-6-1.0×10-1 M. The electrode had relatively short response time ...
a simple, sensitive and selective method for solvent extraction and spectrophotemetric determination of lanthanum (ii) europium (iii), and cerium (iii) is described , the rare earth metals are extracted into chloroform solution of n-phenylbenzohydroxamic acid (pbha) at ph 9-10 various parameters are studied to optimize the extraction conditions. the molar absorptivity is found to increase from ...
